A multicenter, double-blind study compared the antihypertensive efficacy and safety of doxazosin and terazosin as once-daily therapy. Doxazosin, a potent antihypertensive agent, selectively inhibits alpha 1 adrenoceptors. Its pharmacokinetic profile, including gradual onset of action, long plasma elimination half-life and long duration of action, permits once-daily dosing. Terazosin, a structural analog of prazosin, also inhibits alpha 1 adrenoceptors and is recommended as once or twice-daily therapy. Nineteen (73%) of 26 patients randomly assigned to receive doxazosin were therapeutic successes; 17 (65%) achieved normalized blood pressure (defined as blood pressure less than or equal to 90 mm Hg). The mean final daily dosage in patients classified as therapeutic successes was 2.4 mg. Eighteen (64%) of 28 terazosin-treated patients were considered therapeutic successes; 16 (57%) achieved normalized blood pressure. The mean final daily dosage in patients classified as therapeutic successes was 5.6 mg. Treatment-related side effects were observed in 30% of doxazosin-treated and 39% of terazosin-treated patients. Most side effects observed in either treatment group were mild or moderate and either disappeared or were tolerated with continued therapy. Doxazosin is an effective, well-tolerated, once-daily antihypertensive agent; it is comparable with terazosin but at a lower daily dosage.

Anemia is a potentially life-threatening blood disorder caused by an insufficient erythroblast volume in the circulatory system. Self-renewal failure of erythroblast progenitors is one of the key pathological factors leading to erythroblast deficiency. However, there are currently no effective drugs that selectively target this process.

Background: Most young adults with perinatal HIV (PHIV) transition from pediatric or adolescent to adult clinical care. Although guidelines to increase transition success have been recommended, we know little about uptake of these guidelines, particularly by adult care clinics.
Methods: We administered web-based surveys to adult care providers of young adults with PHIV in Massachusetts to evaluate transition preparation and post-transition evaluation practices.

Unlabelled: Human noroviruses (HuNoVs) are the leading cause of acute gastroenteritis worldwide. Currently, there are no targeted antivirals for the treatment of HuNoV infection. Histo-blood group antigens (HBGAs) on the intestinal epithelium are cellular attachment factors for HuNoVs; molecules that block the binding of HuNoVs to HBGAs thus have the potential to be developed as antivirals.

Unlabelled: is a protozoan parasite that causes human and animal African trypanosomiases (HAT and AAT). Cardiac symptoms are commonly reported in HAT patients, and intracardiac parasites with accompanying myocarditis have been observed in both natural hosts and animal models of infection. Despite the importance of as a cause of cardiac dysfunction and the dramatic socioeconomic impact of African trypanosomiases in sub-Saharan Africa, there are currently no reproducible murine models of associated cardiomyopathy.

Merkel cell carcinoma (MCC) is a skin cancer that arises due to either Merkel cell polyomavirus infection (MCPyV) or ultraviolet (UV) radiation exposure, presenting primarily in the head and neck region of fair-skinned males. The recent success of PD-(L)1 immune checkpoint inhibitors (ICIs) in locally advanced/metastatic MCC, with an objective response rate (ORR) around 50% and improved survival, as a first-line treatment has moved ICIs to the forefront of therapy for MCC and generated interest in identifying biomarkers to predict clinical response. The MCC tumour microenvironment (TME) contains various components of the adaptive and innate immune system.
